## Which is better one way slab or two way slab?

While designing a two-way slab we provide more steel hence the depth of the slab decreases, as a result, the thickness of the two-way slab is less as compared to the one-way slab. The one-way slab is economical up to a span of 3.6 meters. Whereas the two-way slab is economical for the panel sizes up to 6m × 6m.

**Where is one way slab and two way slab used?**

Whereas two-way slabs are used in constructive floors of the Multistorey building. In one-way slab quantity of steel is less. In two-way slab quantity of steel is more as compared to the one-way slab. Main Reinforcement is in provide short span due to banding.

**What is the advantages of two way slab?**

Advantages: More efficient structural system than a flat plate, typically with lower stress concentration at column locations. Slabs are generally thinner in comparison to the flat plate solution. Absence of beams allows lower storey heights.

### Where is two way slab used?

Two-way Flat Slabs Thus flat slabs are used for heavier loading and longer span. It requires less concrete, and reinforcement compared to flat plates. However, they need more formwork for capital and panels and take more time to construct than the flat plate. They are used in spans that are square or nearly square.

**Which is best slab?**

Different types of cement are used to construct concrete slabs, but the best would be Portland Pozzolana Cement (PPC). People use PPC to produce concrete for homes, residential areas, and schools. PPC is made of cement clinker (77%), gypsum (3-5%), and fly-ash (20%).

**What is the minimum depth of two way slab?**

For slabs without drop panel 125 mm. For slabs with drop panel 100 mm.

#### What is one way slab used for?

One-way Ribbed Slab (with beams)system is used for the office buildings (low rise), parking structures, and warehouses.

**How one way slab is designed?**

When a slab is supported on all four sides and the ratio of long span to short span is equal or greater than two, it will be considered as one way slab. The load on the slab is carried by the short span in one direction. However main reinforcement bar and distribution bar in transverse direction.

**What is the advantages and disadvantages of one way slab?**

While designing a one-way slab we give less steel henceforth the profundity of the slab increments, accordingly, the thickness of the one-way slab is more when contrasted with the two-way slab. The one-way slab is prudent up to a range of 3.6 meters. In a one-way slab, the amount of steel is less.

## What is one way slab and two slab?

Difference between One Way Slab and Two way slab:

One Way Slab | Two Way Slab |
---|---|

Slabs are supported by the beams on the two opposite sides | Slabs are supported by beams on all the four sides. |

**What is a one way slab?**

One-way slab is a type of concrete slab in which loads are transferred in one direction to the supporting beams and columns. Therefore, the bending occurs in only one direction. The design of one-way slab is simple and can be carried out easily.

**How do you know if a slab is one-way?**

If the ratio of long side / short side > 2 it is considered as one-way slab, and if longer side to shorter side ratio < 2 then it is considered as a two-way slab.

### What is a one-way slab?

**What is normal slab thickness?**

In general, 6 inch (150mm) slab thickness is considered for residential and commercial buildings with reinforcement details as per design. Methods used for finding slab thickness varies for different types of slabs.

**What is the thickness of two way slab?**

Moreover, the minimum thickness of any two way slab without interior beams should not be less than the following: For slabs without drop panel 125 mm. For slabs with drop panel 100 mm.

#### Where one way slab is provided?

Hence, One-way slab is adopted where Cranked bars (main bars) are provided on the shorter side of the slab due to bending. Distribution bars(straight bars) provided on the longer side as shown in fig.

**Where one-way slab is provided?**

**What are the advantages of a one-way slab?**

## What is difference between LSM and WSM?

The cardinal difference between Working state method (WSM) and Limit State method (LSM) is: WSM is an elastic design method whereas LSM is a plastic design method.
